      abstract     = {We present a structural comparison of monolayers on a SiO2
                      substrate of two asymmetrically substituted sexithiophenes
                      (6T). Molecule 1 consists of 6T with a branched alkyl chain
                      at one end only and shows a crystalline structure. In
                      molecule 2, the bifunctional 6T has in addition at the other
                      end a linear alkyl chain. It displays thermotropic liquid
                      crystalline (LC) behavior. Both compounds form readily
                      single molecular layers from solution. Remarkably, full
                      monolayer coverage can be achieved before multilayer growth
                      starts. LC properties promote preordering near the interface
                      as well as exchange of molecules between the growing
                      domains, thus regulating the domain sizes. As a result, the
                      LC compound 2 forms single-molecule islands with larger
                      domain sizes compared to compound 1. Surface X-ray
                      investigations indicate that the 6T cores are tilted
                      relative to the layer normal. The tilt angle is as large as
                      54° for compound 2 compared to 28° for compound 1. For
                      molecule 2, interfacial constraints and packing requirements
                      because of the asymmetric substitution cause a rather
                      loosely organized core structure.},
